CLAMPING DEVICE FOR OIL BUCKETQ.

Application filed September 21, 1922. Serial No. 589,730.v

a device for clamping oil'buckets in place in their containingboxon the rear of an oil truck.

My; invention is designed to eliminate wear upon the box by the movement of the buckets within, by preventing the movement of the buckets. I

Another object is to prevent the batter- 7 ing of the buckets caused by their striking together. 20

With these and other objects in view, my invention consists in the construction, arrangement and combination of the Various parts of my device,.whereby' the objects contemplated are attained, ashereinafter more fully setforth, pointed out in my claims,

and illustrated in the accompanyingdrawings, in which:

Fig. l is a rear elevation of a bucket-retaining box with apair'of buckets therein,

held in place by 'my improved bucket clamp A operative position.

'Fig. 2 is a similar view, the clamp being shown 1n inoperative position.

' Fig. 3 is I a sectional view through the .box showing the clamp in operative position.

Fig. 4 is a similar sectional view showing the'clamp n inoperative position, and

' .ig'. 5. shows a modified form ofthe clamp yoke.

; The ordinary oil delivery truckin general use is made as a tank and at the rear carries a pair of oil buckets which are used to convey the oil or gasoline from the tank to the oil can or gasoline barrel of the customer. These buckets are carried, while thetruck is travelling, in a cablnet or containing box at the rear of the truck.

I have found that the olting of the truck will cause the buckets to move about in the box, impinging against each other, jolting against the sides of the box, and scraping the bottom. As aresult, the buckets become badly dented and worn, and their [capacity decreases as a result of the sides being bent inwardly. The average life of bodied in a the numeral, 10, indicates the forming a shoulder,

the buckets is thus comparatively short, and the box soon becomes badly worn to such an extent that a new one is necessary.

To prevent this wear it is my purpose to provide a clampingdevice which will securely hold them in place.

In general, my invention may be emclamping yoke adapted to engage the tops of the cans, to be held in operative position by a latch, the yoke being mounted on pivoted arms, and having vresilient means for moving it to inoperative position when the latch 1s released.

In Fig. 1 I have shown, generally, a rear view of a bucket-retaining box, in which top of the box, and the numeral, 11, the back thereof. The buckets are indicated in dotted lines at C, only the tops thereof being shown. Ordinarily there are two buckets which are received in the box side by side, as shown in Fig.1, in which the box is viewed from the rear of the truck. The yoke, R, extends between the buckets and engages the tops thereof, as shown in Fig. 1.

The yoke, R, is preferably formed of an angle bar, and is supported by the arms, A, which are riveted or, otherwise secured to the lower flange of the yoke. Hinges, B,

"serve to connectthe arms, A, to the rear 1 slidable longitudinally thereon.

The member, 16, has an offset portion '17, which is inclined from the perpendicular, as shown. The member, 16, terminates in a downwardlyprojecting finger, 18, which serves as a handle. 7

When the clamping device is not .in use, the parts are. held in raised position in the corner of the box, as illustrated in Fig. 4. The spring, 5, serves to draw the latch inwardly and upwardly, and the latch engages the yoke, R, and pushes it tothe position shown.

When the yoke, R, is drawn downwardly against the latch, the latch will be pushed outwardly till the the shoulder, 17,. when the latch will be Ill) yoke has slipped under of the yoke, in which the yoke, R

drawn inwardly by the spring, S, and the inclined shoulder, 17, will force the yoke down against the buckets, C, so as to hold them securely against the bottom of the box.

When the latch is drawn outwardly, the spring, S, which connects the yoke and latch as shown, wlll draw the yoke upwardly to a posit-ion where its inclination relative to the latch willallow it to be moved upwardly under the pressure of the latch against it.

It will beseen from the foregoing that the cl mp may be brought into operation by merely placing the hand upon the yoke and drawing it downwardly. In order to cause the parts to resume moperative position, the latch is simply drawn outwardly sufliciently to release the yoke from the shoulder, 17, and then released.

In Fig. 7, l have shown a modified form has pivja-ws, B The oted to its endsthe clamp R, are faced jaws, R andthe clamp jaws, underneath with leather, 20. I

It will be seen that my device is semiautomatic in its operation, the parts being almost entirely controlled by springs. This feature increases the utility of the device greatly and renders it more desirable.

The parts may be adjusted to fit different sizes of boxes.

Some changes struction andtarra-ngement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. In a device of the class described to be used in combination with a bucket-retaining box, a yoke, and a latch, each being hinged at points spaced from each other tioned so thatthe paths of the yoke and the outer portion of the latch cross each other at a point wherethe'yoke is in position to engage a bucket in the box, means on the latch to hold the yoke in such position, the latch being positioned to engage the yoke and move it to inoperative position, and resilient means, to move the latch to inoperative position.

2. In a device of the class described to be 7 used in combination with a bucket-retaining box, a yoke and a latch, each being hinged at points spaced from each other and positioned so that the paths of the yoke and the outer portion of the latch cross each, other at a point where the yoke is in position to engage a bucket in the box, means on the latch to hold the yoke in such position, the

latch being positioned to engage the yoke and move it to inoperative posltion when the yoke has swung across the path of move- ,move the latch toward said plane,

may be made in the congage a bucket in the box,

and posi- 4 ment of the latch, means for moving the yoke across the path of movement of the latch when the latch is released, and resilient means to move the latch to inoperative position.

3. In a device-of the class described, a yoke and a latch pivoted on axes spaced from each other for swinging motion to ward the plane joining their axes, the yoke being normally positioned between the latch and saidplafne, resilient means tending to and means on the latch to lock the yoke and latch against movement toward said plane when the yoke has been moved away from said plane to a predetermined position.
